03-06 Wrangler Rear Seat Subwoofer Box

The 33 Engineering "In Seat" Sub Box is continuing innovation to help take your Jeep's sound system to the next level. There are many things to consider when adding sound to your Jeep, but in our opinion the foremost concern should be security. With our custom designed box, you will be able to fit 8 or 10 inch woofers into the rear seat of your jeep without sacrificing any storage space! That's right! NONE! Because the sub box fits inside the rear seat, not only do you keep it out of sight, but you won't lose the use of any functionality of your Wrangler.

Installation: To install this sub box, you will need to remove some of the foam from the rear seat. Approximately 1.5" of foam is left in tact, so your seat is still very functional and comfortable to sit in. The seat height will be raised about 2 to 3 inches from the installation. There are modifications necessary to the seat frame to get the box to fit. Please see our installation instructions for more information.

Recommended Subwoofers: The sub enclosure was designed to .65 cubic feet. Many subwoofer combinations will work, but getting the box to sound good will require careful selection of your subwoofers. The chart below has been designed to help our customers make this choice. Pay special attention to the right most column, Recommended Qty. This column is our recommendation of how many of this type of woofer should ideally be put into the box. If you're interested in the Pioneer woofer highlighted in the chart, we've built a special box for them that don't require seat spacers.
